Update Manager runs with the default configuration properties if you have not modified them during the installation. You can modify the Update Manager settings later from the Update Manager Administration view.
You can configure and modify the Update Manager settings only if you have the privileges to configure the Update Manager settings and service. These permissions must be assigned on the vCenter Server system with which Update Manager is registered. For more information about managing users, groups, roles and permissions, see vSphere Security documentation. For a list of Update Manager privileges and their descriptions, see Update Manager Privileges.
If your vCenter Server system is connected to other vCenter Server systems by a common vCenter Single Sign-On domain, and you have installed and registered more than one Update Manager instance, you can configure the settings for each Update Manager instance. Configuration properties you modify are applied only to the Update Manager instance you specify and are not propagated to the other instances in the group. You can specify an Update Manager instance by selecting the name of the vCenter Server system with which the Update Manager instance is registered from the navigation bar.
